Information
Fumed silica is an important superfine inorganic material which is synthesized by the vapour phase pyrohydrolysis of halogenatedsilanes in hydrogen oxygen flame. It is a nanoscaled amorphous silica with uniform distribution, high specific surface area and high surface activity.

About Fumed Silica
11Hifull
Specializing in Quality, Technology Driven Hydrophilic and Hydrophobic Fumed Silica
Hubei Huifu Nanomaterial Co., Ltd. (former company name: Yichang Huifu Silicon Material Co., Ltd.) is a professional manufacturer of high quality fumed silica with 20 years of expertise. Hifull is committed to scientific improvement and developing new and improved grades. As one of the largest manufacturers of fumed silica in China, Hifull's hydrophilic and hydrophobic fumed silica have been used in many industries, which include products such as, special rubber, printing ink, coatings, silicon rubber, and industrial adhesives. Our product has been sold to 50+ countries and regions of the world.
 
2222Hydrophilic Fumed Silica
Hydrophilic Fumed Silica is a white colloidal powder. It can be dissolved in water. This fumed silica has properties that include much or less of the following: reinforcing filler in elastomers, anti-settling or anti-sagging agents, improved free flow and anti-caking characters of powders, transparency in unsaturated polyester resins, and reinforcing filler in elastomers, rheology and thixotropy control of liquid systems, binders, polymers. It is applicable in the coatings and paint or sealants and adhesives industry. Select types of silica are also suitable with HTV and RTV silicone rubber, cosmetics, fertilizers, and various other sectors.
 
 
3333
Hydrophobic Fumed Silica
Hifull's Hydrophobic Fumed Silica is a structure modified hydrophobic silica treated with either HMDS (Hexamethyldisilazane), DDS (Dimethyldichlorosilane), or silicone oil. Depending on the selection chosen, the properties for this silica can provide a low thickening effect, excellent reinforcing in silicone rubber, free-flow aid for powders, good anti-sagging properties, stability in epoxy resin, good thickening, high water resistance in powders, and more. Hydrophobic fumed silica from Hifull are applicable with silicone rubber, toner, anti-foamer, vinyl ester resins, toners, coatings and printing, and greases.
